HOLLY SPRINGS, N.C. (AP) -- Federal nuclear regulators say an outside contractor hired to look for problems in a Duke Energy nuclear reactor in North Carolina missed a quarter-inch spot of corrosion and cracking near the reactor core that forced a full shutdown last month.
 
Nuclear Regulatory Commission inspectors said Thursday they're still trying to figure out why the problem at the Shearon Harris nuclear plant near Raleigh wasn't caught by later reviews. A final NRC inspection report will be released by mid-July.
 
Inspectors said during a public meeting that four smaller spots were fixed during a refueling shutdown last year, but the flaw that forced the May 15 shutdown wasn't found until new contractors reviewed tests from last year.
 
The NRC say radiation never leaked. The plant returned to full power Sunday.
